Abstract

Die vorliegende Erfindung betrifft ein wärmeerzeugendes Element einer Heizvorrichtung zur Lufterwärmung umfassend wenigstens ein PTC-Element (6) und an gegenüberliegenden Seitenflächen des PTC-Elementes (6) anliegende elektrische Leiterbahnen (4). Ein hinsichtlich der Sicherheit gegen elektrische Überschläge verbessertes wärmeerzeugendes Element wird mit der vorliegenden Erfindung dadurch geschaffen, dass die beiden elektrischen Leiterbahnen (4) außenseitig von einer nicht leitenden Isolierschicht (8) umgeben sind. Die Erfindung verbessert ferner eine Heizvorrichtung zur Lufterwärmung mit mehreren wärmeerzeugenden Elementen (56) umfassend wenigstens ein PTC-Element (6) und an gegenüberliegenden Seitenflächen des PTC-Elementes (6) anliegende elektrische Leiterbahnen (4) und mehreren in parallelen Schichten angeordneten wärmeabgebenden Elementen (56), die an gegenüberliegenden Seiten des wärmeerzeugenden Elementes (56) angelegt gehalten sind. Die wärmeabgebenden Elemente sind gemäß der Erfindung im Wesentlichen potentialfrei und mit höherer Sicherheit gegenüber elektrischen Überschlägen dadurch gesichert, dass die wärmeabgebenden Elemente (56) unter Zwischenlage jeweils einer Isolierschicht (8) an den gegenüberliegenden Seiten des wärmeerzeugenden Elementes (60) anliegen (Fig. 3).
